o2 sensor + idle air control

[Viper5]

I bought a 2000 boxster s a couple months ago and it is having minor problems. I have the durametric which gives me codes and lets me reset. The guy I bought it from said that o2 sensor will come on, but he just reset it to make it go away since he didnt want to buy another one.

The first time I checked the codes since the CEL came on, I noticed that the o2 sensor error (p1115) was there alongside another one labeled idle air control system (p0507). I spoke to the guy I bought it from and he said he didn't know about the p0507 error.

They are both related to the air system and I was thinking they were related. Is it possible that if I fix the o2 sensor, then the other one will go away?

I found one really cheap here but don't know if it is going to be difficult to install since the other end doesn't match what the oem end looks like.

Any advice would be appreciated.
